Fluticasone starts working after 12 hours. However, it may take several days of continued usage to experience the full benefits and most people do not see the full benefits until 10–14 days of continuous, daily usage. If it is working, you will experience an improvement in your nasal congestion. Please see the full Prescribing Information for more information.
